IMPROVEMENT IN SCRAPERS FOR DOOR-MATS.

Specification forming part of Letters Patent No. 223, [54. datedDecember 30, 1879; application filed October 18, 1879.

To all whom it may concern:

Be it known that 1, WILLIAM E. LAWRENCE, of the city, county, and Stateof New York, have invented an Improvement in Scrapers for Door-Mats, ofwhich the following is a specification.

My invention relates to that class of mats illustrated in the patentgranted to C. J. Ferguson on the 26th day of August, 1879; and

my invention consists in constructing the scraper so that it may readilybe applied and secured to the mat, whether the latter be of the ordinaryform or specially adapted to receive it.

In the drawings forming part of this invention, Figure 1 shows, inperspective, a doormat and scraper applied thereto; Fig 2, a transversesection of Fig. 1; Fig. 3, a perspective view of the scraper; and Figs.4 and 5, sections showing modifications.

The aforesaid patent granted to Ferguson shows and claims a combined matand scraper, the latter being shown as of peculiar construction. Tofacilitate and cheapen the manufacture of mats of this character, I makethe scraper A of cast metal, in one or more pieces, with a series ofupright blades, 5, connected by cross-bars 0, the whole constituting aribbed frame. To facilitate the attachment of the scraper to the mat, itmay be provided with pointed lugs to, projecting upward or downward.

Where the scraper is to be applied to the top of the mat the lugsproject downward from the frame, so as to penetrate the pile or face, asshown in Fig. 4.

In some instances the pile of the mat may be cut away, forming a recessfor the admission of the scraper, which rests upon the up per face, 01,of the body of the mat, oris supported above the same by the lugs a,which penetrate the back, as shown in Fig. 5.

When it is desired that the scraper shall be inserted from the bottom,the frame is extended to form a lower flange, d, from which the lugs aproject upward, and the mat is cut away to form a recess adapted toreceive the portion of the scraper that extends above the flange d. Whenthus applied the body of the mat rests upon the flange d, so that thescraper cannot be lifted through the mat while the lugs Ct, as in theother forms, serve to retain the scraper in its position withoutinterfering with its ready removal.

In the form represented in Figs. 1 to 3 the blades b are supported atsome distance above the bottom of the mat, leaving a receptacle beneath,in which the scrapings may collect, and a pan may be placed in thisreceptacle, so as to facilitate the removal of the scrapings; or thebottom and sides of the scraper may be closed, so as to constitute thereceptacle.

It will be apparentthat by casting the scrn per in one piece it may beproduced very cheaply, and that the construction above described permitsit to be readily applied, securely retained, and easily detached whennecessary for cleaning.

When it is not required to detach the scraper it may be permanentlysecured, as, for instance, by bolts 1', as shown in Fig. 5.

I claim-- I 1. The scraper A, consisting of a series of blades, 1), casttogether in one piece, and adapted for application to a door-mat,substantially as set forth.

2. The scraper provided with the blades 1), connected together andhaving lugs a, substantially as set forth.

3. The combination,in the scraperA, of the blades 1), connectedtogether, and the lower horizontal plate or flange, d, substantially asset forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WM. E. LAWRENCE.
